Single-sphere neutron spectrometer instead of a full Bonner sphere set
Active neutron spectrometer in which 32 silicon detectors in six layers inside one moderating sphere reproduce the spectrometric performance of a six-sphere Bonner set. It measures the neutron spectrum from thermal up to 10 GeV (20 MeV in the LITE version), has built-in electronics and can show the spectrum and H*(10) in real time. It tolerates a high gamma background.
